IMPROVEMENT IN REVOL/VING FIRE-ARMS.

Specification forming part of Letters Patent No. 20,4196, dated June S, 1858.

To all whom it may concern.-

Be it known that I, MOSES KINSEY, otl Newark, in the county of Essex and State of New Jersey, have invented 'a new and useful lmprovement in Revolving-Cylinder Fire-Arms; and I do hereby declare that the following is a full; clear, and exact description of the same, reference being had to the accompanying drawings, forming part ot' this specification, in which- Figure l is a longitudinal central section of a pistol with my improvement. Fig. 2 is atransverse section of the same in the linexaof Fig. 1. Fig. 3 is a side view of the ratchet-` To enable others to make and use my inven-A tion, I will proceed to describe its construction and operation.

A is the metal frame which contains the cylinder C, and forms the principal portion of the stock, and into which the barrel B is screwed.

S is the main spindle, which is inserted through the back of the frame A, and through a hole bored through the axis of the cylinder, and enters a bearing in the front part of the frame. This spindle has a square or iiat.

formed upon it at a in Fig. 1, to lit into a corresponding square or flat in the bore of the cylinder to compel said cylinder to turn with it and it has formed upon or securely attached to its rear portion a ratchet-wheel, D, with teeth on its front face corresponding in number with the chambers c c in the cylinder C, and between the back of this ratchetwheel and the projecting head al of said spindle, which permits it to be laid hold of to draw it out of the cylinder, is formed a groove, e, which receives the point ot a screw, f, that is screwed into the frameA for the purpose of preventing the drawing out of the spindle, but which permits the rotation thereof. By taking out this screw permission to withdraw the spindle for the purpose of taking out the cylinder is obtained.

E is the ha1nmer,which turns freely on a pin, g, which passes through one side ot' the frame A and screws into a movable plate, F, which can be taken oif to expose the lock by unscrewing the said pin from it. The hammer is made with a deepy boss, h, on one side, as shown in Fig. 2, which boss contains a hole to receive a pin, t', which is rmly secured to the dog G, by which the rotation and stoppage of the cylinder C is effected, the said pin serving to attach said dog to thehammer, that the dog may be operated to rotate the cylinder by the cooking of the hammer. The dog G hasthe tooth j, which acts uponthe ratchet-wheel D to rotate the cylinder formed at its upper extremity, and the said tooth performs its duty by the upward movementof the dog produced by drawing back the hammer to cock it. The dog operates on the opposite side of the main spindle S to the hammer. lt is kept in contact with the ratchetwheel by thespring k, which is attached to the said dog, and which bears against the portion of frame A which constitutes the recoilshield to the cylinder. l

Some distance below th'e tooth j is the stoptooth k, which constitutes my invention, said tooth standing out from the side of the said dog toward the hammer in such a position that as the hammer arrives at full-cock and the dog completes the rotation of the breech the next tooth but one in arrear of that which has been operated upon by the4 tooth j to produce the rotation arrives in contact with it la and prevents the cylinder rotating beyond the proper point by the momentum it may have acquired. To make the tooth 7c operative on the ratchetwheel the backs of said teeth are not inclined all the way to their bases, but at the bottoms are formed square with the bases, asshown at n n, in Fig. 3.

j l is the spring-stop usually employed to prevent the return of the cylinder with the parts of' the backs of the teeth of' the ratchetdog,.as the latter returns when the hammer whee1D,in the manner and forthc purpose defalls. pose described.

What I claim as my invention, and desire t0 secure by Letters Patent, is- MOSES KINEY' Furnishing the dog Gr With the additional Witnesses:

tooth 7c, arranged t-o operate in combination W. TUSCH, with square or equivalentiy-formed bottom W. HAUFF.
